    If you replaced all of the fuses than your pig tail is loose , unhook it then blow it out and connect it back firmly into the electrical socket

    The flasher control module for the trailer is in that box under the hood too, 1 flasher unit for each side of truck, try swapping them over.

    Before thinking the worst just replace and check all of the small parts; Lol $20 fix over a $125 check and advise from freightliner any day.
